<p>The video recorder has two rotary magnetic heads (01, 02) which are diametrically opposed so as to cooperate with successive, parallel, oblique tape tracks. A third rotary head (03) allows signals to be recorded on or read from the second of these tape tracks, when the magnetic tape (05) is still, the two former heads (01, 02) alternately scanning the first tape track. Pref. the third rotary head (03) rotates within a plane which is spaced from the plane of rotation of the first two rotary heads (01, 02) and is balanced by a counter-weight.</p> |
